Spirometry

Question 1

is the volume of air inspired (or expired) during normal quiet breathing (500 ml).

Answer 1

Tidal volume

Question 2

is the volume inspired during a very deep inhalation (3100 ml – height and gender dependent).

Answer 2

Inspiratory Reserve Volume (IRV)

Question 3

is the volume expired during a forced exhalation (1200 ml).

Answer 3

Expiratory Reserve Volume (ERV)

Question 4

is all the air that can be exhaled after maximum inspiration.
It is the sum of the inspiratory reserve + tidal volume + expiratory reserve
(4800 ml).

Answer 4

Vital capacity

Question 5

is the air still present in the lungs after a force exhalation (1200 ml).

Answer 5

Residual volume

Question 6

The process of taking air into the lungs

Answer 6

Inspiration

Question 7

The process of letting air out of the lungs during the breathing cycle

Answer 7

Expiration

Question 8

The number of breaths, a person takes per minute

Answer 8

Breathing rate
